Bringing up the past in fresh marital arguments

Some people find it difficult to forgive and forget past issues. A woman once complained that her husband always brings up the past whenever they have any argument. He always reminds her of mistakes she made decades ago and this, often, tend to lead to a bigger disagreement and argument.

The very first time they had a quarrel when they just got married, she begged him for forgiveness and her husband said he had forgiven her, you can imagine how she felt when he later made much reference to the issue much later.

She felt really hurt because it made her realise her husband never forgave her, even when he claimed he had. Such can cause a great strain to a relationship. 

We need to realise that the matter that we have already resolved should never be referred to again. It is not as if your mind will not wander there, but when it does, hold it back and tackle the new matter on the ground.

Accept the apologies of those that have offended you, forgive them and forget about it. 
Learn not to reflect on the past, it is an act of emotional maturity. Love you!
